Some of the Mac specific parts are in Objective C (Cocoa).

The problem is that SDL seems to be written in objective-C,
and when I compile it gives me:

ld: /usr/lib/crt1.o illegal reference to symbol:
__objcInit defined in indirectly referenced dynamic library
/usr/lib/libobjc.A.dylib

Does anyone know how to glue my C++ project to SDL?

I've never used SDL with C++, and I actually know very little about C++,
but anyway: You need to link your application with the Cocoa
framework, are you doing that? "-framework Cocoa" on the command line,
or add the Cocoa framework to the project in Xcode.

You probably need to add '-lobjc' to your CFLAGS, to link in the ObjC
lib.

Use "-framework Cocoa" ... don't link with the Objective C runtime directly.
